loop () function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board.

In this article, we will discuss while loops, do while loops, for loops. We will see how to use these loops in an Arduino program with an example project that blinks an LED only when a button is pressed.

Nov 8, 2024 · The for statement is used to repeat a block of statements enclosed in curly braces. An increment counter is usually used to increment and terminate the loop. The for statement is useful for any repetitive operation, and is often used in combination with arrays to operate on collections of data/pins. // statement(s);

Loops are very important control structure in any programming language. It helps to keep our code small, handy and pretty easy to write and understand. There are loops in Arduino programming language as well. How a loops works is shown below with the help of flowchart. It is the basic logic for loops.

Nov 8, 2024 · After creating a setup() function, which initializes and sets the initial values, the loop() function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board. Serial.begin(9600); pinMode(buttonPin, INPUT); if (digitalRead(buttonPin) == HIGH) {

Save rewriting code with a for-loop. Avoid off by one errors - very easy to miss. Count up or down (and use the loop variable inside code). Find out where you can use for-loops. Access array data with a for-loop. The 'for loop' is one of those bread-and butter functions that you will use all the time in your code.

Oct 7, 2024 · In this article, you’ll learn about the commonly used loops in Arduino: for loop. while loop. do...while loop. loop() function. for Loop vs while Loop – Which One Should You Use? Here’s the syntax for a for loop:

Apr 23, 2025 · Connect six LEDS, with 220 ohm resistors in series, to digital pins 2-7 on your Arduino. The code below begins by utilizing a. loop to assign digital pins 2-7 as outputs for the 6 LEDs used. In the main loop of the code, two. loops are used to loop incrementally, stepping through the LEDs, one by one, from pin 2 to pin seven.

Mar 13, 2025 · Loops allow you to execute a block of code multiple times based on a condition. This tutorial explores the different types of loops available in Arduino, their syntax, and practical use cases with examples. 1. What Are Loops? 2. Types of Loops in Arduino. 3. Nested Loops. 4. Practical Examples. 5. Break and Continue in Loops. 6.

In my experience with Arduino programming, mastering the For Loop is a fundamental skill. This control structure enables the repeated execution of code blocks, facilitating automation and enhancing the dynamism of my projects. In this guide, I explain the Arduino For Loop from its basics to advanced applications.
